BACKGROUND Technical Field

The present invention relates to a display device and, morespecifically, to a display device having a shaped sealing member.

Discussion of the Related Art

Display devices may be applied to portable electronics such as smartphones, smart watches, tablet PCs, and notebook computers, or largeelectronic devices such as televisions, monitors, and digitalinformation displays.

Recently, display devices have been designed to have a slimmer bezel soas to provide electronic devices with a wider screen without increasingthe size of the electronic device.

As display devices are often used in portable electronics, such assmartphones, in which a speaker module and one or more optical sensorsare disposed, one method for reducing bezel size is to create a displaydevice having a display area that is atypically shaped to have a notchor trench shape in a top region thereof. However, when the display areais atypically formed, the durability of the display device maydeteriorate.

FIG. 1 is an exploded perspective view illustrating a display device 1according to an exemplary embodiment of the present invention. FIG. 2 isa cross-sectional view illustrating the display device 1 of FIG. 1 ,taken along line II-II′ in FIG. 1 . FIG. 3 is a cross-sectional viewillustrating the display device 1 of FIG. 1 , taken along line III-III′in FIG. 1 . FIG. 4 is a plan view illustrating a first base substrate111 of a light-emitting substrate 101 of FIG. 1 . FIG. 5 is a plan viewillustrating a second base substrate 211 of a counter substrate 201 ofFIG. 1 .

Referring to FIGS. 1 to 5 , in the display device 1 according to anexemplary embodiment of the present invention, a display area DA and anon-display area NA (See, for example, FIG. 2 ) may be defined.

The display area DA may include a plurality of pixels and may provideimage display. As used herein, the term “pixel” refers to a smallestunit area for generating a point of color. Each pixel may express apredetermined basic color. Examples of the basic color may include, butare not limited to, red, green, and blue. In an exemplary embodiment ofthe present invention, in a plan view, the display area DA may have ashape in which one side edge (for example, a lower edge in FIG. 4 ) ispartially indented. For example, one side edge of the display area DA inthe second direction Y may have an atypical shape such as a bay, anotch, or a trench, in a plan view.

In a plan view, the display area DA may be at least partially surroundedby the non-display area NA. The non-display area NA refers to an areanot contributing to image display. The non-display area NA may include asealing area SA in which a sealing member 301 is disposed, an innernon-display area INA located inward from the sealing area SA (e.g.,between the display area DA and the sealing area SA), and an outernon-display area ONA located outward from the sealing area SA.

In an exemplary embodiment of the present invention, the display device1 includes a light-emitting substrate 101, a counter substrate 201disposed over the light-emitting substrate 101, and a sealing member 301disposed between the light-emitting substrate 101 and the countersubstrate 201 and coupling the light-emitting substrate 101, and thecounter substrate 201. The display device 1 may further include a firstflexible circuit film 401, a second flexible circuit film 501, and amodule member 601.

The light-emitting substrate 101 (for example, a first substrate) mayinclude a light-emitting element 190 capable of emitting light by itselfto provide light necessary for image display. For example, thelight-emitting substrate 101 may be a display substrate including thelight emitting elements 190 disposed at each pixel. The light emittingelements 190 disposed at each pixel may emit light independently of eachother, thereby implementing image display and color expression.

The first base substrate 111 may provide a space for stably disposingthe light emitting element 190 and the like. The upper surface of thefirst base substrate 111 may be placed in a plane to which the firstdirection X and the second direction Y belong. The first base substrate111 may be a transparent or opaque insulating plate or insulating film.For example, the first base substrate 111 may include a glass material,a quartz material, or the like. For example, the first base substrate111 may include a polymer material such as an imide resin, a carbonateresin, and/or an acrylic resin.

In an exemplary embodiment of the present invention, in a plan view, thefirst base substrate 111 may include a main portion 111 a (see, FIG. 4 )having a first maximum width W_(111a) in the first direction X, a firstprotruding portion 111 b protruding from the main portion 111 a in thesecond direction Y, and a second protruding portion 111 c protrudingfrom the main portion 111 a in the second direction Y and spaced apartfrom the first protruding portion 111 b in the first direction X. Thefirst protruding portion 111 b of the first base substrate 111 may havea second maximum width W_(111b) in the first direction X, and the secondprotruding portion 111 c thereof may have a third maximum width W_(111b)in the first direction X. Each of the second maximum width W_(111b) andthe third maximum width W_(111b) may be smaller than the first maximumwidth W_(111a). For example, the sum of the second maximum widthW_(111b) and the third maximum width W_(111c) may be smaller than thefirst maximum width W_(111a). The second maximum width W_(111b) and thethird maximum width W_(111c) of the first base substrate 111 may be thesame as or different from each other. In addition, the first basesubstrate 111 may have a shape in which the maximum length thereof inthe second direction Y is longer than the length thereof in the firstdirection X, for example, the first maximum width W_(111a).

At least a part of the display area DA of the display device 1 mayoverlap the first protruding portion 111 b and second protruding portion111 c of the first base substrate 111. For example, pixels are definedin the first protruding portion 111 b and second protruding portion 111c of the first base substrate 111 as well as in the main portion 111 aof the first base substrate 111, and each of these three portions maycontribute to image display and color expression. While the display areaDA is not formed to overlap the module member 601, the display area DAis formed adjacent to the module member 601 along three sides thereof(two sides in the first direction X and 1 side in the second directionY), thereby minimizing the planar area of the non-display area NA andincreasing the planar area of the display area DA.

One side edge (for example, a lower edge in FIG. 4 ) of the display areaDA in the second direction Y may have an atypical shape such as a bay, anotch, or a trench, in a plan view. For example, one side edge 121 ofthe first base substrate 111 may be partially indented. For example, oneside edge 121 of the first base substrate 111 may include a first edge121 b, a second edge 121 a indented from the first edge 121 b, and athird edge 121 c protruding from the second edge 121 a.

The first edge 121 b refers to one side edge of the first protrudingportion 111 b of the first base substrate 111 in the second direction Y,the second edge 121 a refers to one side edge of the main portion 111 aof the first base substrate 111 in the second direction Y, and the thirdedge 121 c refers to one side edge of the second protruding portion 111c of the first base substrate 111 in the second direction Y. The firstprotruding portion 111 b, second protrusion portion 111 c and secondedge 121 a of the first base substrate 111 may together form a bay.

In an exemplary embodiment of the present invention, the shortestdistance D₁ from the first edge 121 b to the display area DA in thesecond direction Y may be larger than the shortest distance D₂ from thesecond edge 121 a to the display area DA in the second direction Y.Further, the shortest distance from the third edge 121 c to the displayarea DA in the second direction Y may be larger than the shortestdistance D₂ from the second edge 121 a to the display area DA in thesecond direction Y.

As will be described later, the shortest distance D₁ from the first edge121 b to the display area DA is larger than the shortest distance D₂from the second edge 121 a to the display area DA, thereby sufficientlysecuring the width of a portion extending in the first direction X (forexample, a first linear portion 311 to be described later) of thesealing member 301 disposed on the first protruding portion 111 b.Further, a light-emitting substrate pad unit 170 is not disposed betweenthe second edge 121 a and the sealing member 301, thereby securing aspace for disposing the module member 601 between the first protrudingportion 111 b and second protruding 111 c of the first base substrate111.

A driving layer including a thin film transistor 130, wirings 150, and alight-emitting substrate pad unit 170 may be disposed on the first basesubstrate 111. For convenience of explanation, although FIG. 2 and thelike show one thin film transistor 130, in some exemplary embodiments ofthe present invention, the driving layer may further include a pluralityof thin film transistors and/or auxiliary electrodes for forming acapacitor or a bridge.

The thin film transistor 130 may be electrically connected to thelight-emitting element 190. For example, the thin film transistor 130may be a driving transistor configured to control the amount of currentprovided to the light-emitting element 190 in a specific pixel. However,the present invention is not limited thereto, and the thin filmtransistor 130 may be a switching transistor configured to control aspecific pixel to be on or off, a compensation transistor forcompensating a driving signal, an initialization transistor in which aninitializing signal is applied to a gate electrode, or a light emissioncontrol transistor in which a light emission control signal is appliedto a gate electrode.

The thin film transistor 130 may include an active layer 131 for forminga channel, a gate electrode 135 which is a control terminal, a sourceelectrode 137 which is an input terminal, and a drain electrode 139which is an output terminal.

The active layer 131 may be disposed on the first base substrate 111.Although FIG. 2 and the like show a case where the active layer 131 isdirectly disposed on the first base substrate, alternatively, at leastone inorganic layer may be disposed between the first base substrate 111and the active layer 131. The active layer 131 may include asemiconductor material. For example, the active layer 131 may includepolycrystalline silicon, or may include an oxide semiconductor.

The gate electrode 135 may be disposed on the active layer 131. The gateelectrode 135 may at least partially overlap the channel region of theactive layer 131 in the third direction Z. The gate electrode 135 mayinclude aluminum, molybdenum, copper, titanium, and/or an alloy thereof.The gate electrode 135 may be formed of a single layer, or may have alaminate structure including a plurality of layers. The gate electrode135 may constitute a control terminal configured to carry a controlsignal of the thin film transistor 130. In an exemplary embodiment ofthe present invention in which the thin film transistor 130 is a drivingtransistor, the gate electrode 135 may be electrically connected to anoutput terminal of a switching transistor for controlling a specificpixel to be on or off. A first insulating layer 140 is interposedbetween the active layer 131 and the gate electrode 135 to insulate themfrom each other. The first insulating layer 140 may be a gate insulatinglayer. The first insulating layer 140 may include an inorganicinsulating material. The inorganic insulating material may includesilicon nitride, silicon oxide, silicon oxynitride, and/or siliconoxynitride.

The source electrode 137 and the drain electrode 139 may be disposed onthe gate electrode 135. The source electrode 137 and the drain electrode139 are electrically connected to the source region and the drain regionof the active layer 131, respectively, and may be spaced apart from eachother. Each of the source electrode 137 and the drain electrode 139 mayinclude aluminum, molybdenum, copper, titanium, and/or an alloy thereof.Each of the source electrode 137 and the drain electrode 139 may beformed of a single layer or may have a laminate structure including aplurality of layers. The source electrode 137 may constitute an inputterminal to which the input signal of the thin film transistor 130 isapplied, and the drain electrode 139 may constitute an output terminalto which the output signal of the thin film transistor 130 is applied.In an exemplary embodiment of the present disclosure in which the thinfilm transistor 130 is a driving transistor, the source electrode 137may be electrically connected to a driving voltage wiring configured tocarry a driving voltage, and the drain electrode 139 may be electricallyconnected to the anode 191 of the light-emitting element 190.

An interlayer insulating layer 160 including a second insulating layer161 and a third insulating layer 163 may be interposed between the gateelectrode 135 and the source electrode 137 and between the gateelectrode 135 and the drain electrode 139. The interlayer insulatinglayer 160 may isolate the gate electrode 135, the source electrode 137,the drain electrode 139, and auxiliary electrodes from each other. Eachof the second insulating layer 161 and the third insulating layer 163may include an inorganic insulating material. The inorganic insulatingmaterial may include silicon nitride, silicon oxide, silicon oxynitride,and/or silicon oxynitride.

A protective layer 181 may be disposed on the source electrode 137 andthe drain electrode 139. The protective layer 181 may cover the sourceelectrode 137 and the drain electrode 139 to prevent the sourceelectrode 137 and the drain electrode 139 from coming into contact withan organic material.

The wirings 150 may be located at least partially in the non-displayarea NA, for example, the outer non-display area ONA. The wirings 150may extend from the non-display area NA to the display area DA totransmit a signal provided from an external driving element to the thinfilm transistor 130 or the like. For example, the wirings 150 may beelectrically connected to the light-emitting substrate pad unit 170 totransmit a signal provided from the first flexible circuit film 401 tothe thin film transistor 130 or the like. The wirings 150 may include ascan wiring configured to carry a scan signal, a data wiring configuredto carry a data signal, and a drive voltage wiring configured to carry adrive voltage. FIG. 2 and the like illustrate a case where the wirings150 are disposed on the same layer as the source electrode 137 and thedrain electrode 139, but the present invention is not limited thereto.

The light-emitting substrate pad unit 170 (for example, a first padunit) may be disposed in the non-display area NA. For example, thelight-emitting substrate pad unit 170 may be disposed entirely withinthe outer non-display area ONA. In this case, the wirings 150electrically connected to the light-emitting substrate pad unit 170 maybe arranged to cross the sealing area SA. In some exemplary embodimentsof the present invention, the light-emitting substrate pad unit 170 mayinclude a pad electrode. The pad electrode has an expanded area, and maybe electrically connected to the wirings 150 through a contact holeformed in the protective layer 181. However, the present invention isnot limited thereto, and alternatively, the ends of the wirings 150 mayextend to form the light-emitting substrate pad unit 170 for electricalconnection.

Further, the light-emitting substrate pad unit 170 may be disposedadjacent to one side edge 121 of the first base substrate 111 in thesecond direction Y. In an exemplary embodiment of the present invention,the light-emitting substrate pad unit 170 is disposed adjacent to thefirst edge 121 b and the third edge 121 c of the first base substrate111, but might not be disposed adjacent to the second edge 121 a. Forexample, in a plan view, the light-emitting substrate pad unit 170 isdisposed between the first edge 121 b and the sealing member 301 andbetween the third edge 121 c and the sealing member 301, but might notbe disposed between the second edge 121 a and the sealing member 301.The light-emitting substrate pad unit 170 is disposed on the firstprotruding portion 111 b and the second protruding portion 111 c of thefirst base substrate 111, but is not disposed on the main portion 111 a,thereby minimizing the shortest distance D2 from the second edge 121 ato the display area DA and reducing the area of the non-display area NA.In addition, a space for disposing a module member 601 is accordinglyprovided.

A step compensating layer 183 may be disposed on the wiring layer. Thestep compensating layer 183 has a step compensating function for atleast partially compensating the step formed by the driving layerincluding the thin film transistor 130 and the like, and may provide aspace for stably disposing the light-emitting element 190. The materialof the step compensating layer 183 is not particularly limited as longas it has high light transmittance and has step compensatingcharacteristics and insulating characteristics, but examples thereof mayinclude organic materials such as an acrylic resin, an epoxy resin, animide resin, a cardo-based resin, and an ester resin.

The light-emitting element 190 may be disposed on the step compensatinglayer 183. The light-emitting element 190 may include an anode 191 (forexample, a lower electrode), a cathode 193 (for example, an upperelectrode), and a light-emitting layer 195 interposed between the anode191 and the cathode 193. For example, the light-emitting layer 195 maybe an organic light-emitting layer including an organic light-emittingmaterial, and the light-emitting element 190 may be an organiclight-emitting element. The light-emitting element 190 may emit onlyblue light, emit only green light, emit only red light, or emit whitelight mixed therewith, depending on the material or laminate structureof the light-emitting layer 195.

The anode 191 may be a pixel electrode disposed for each pixel andprovided with driving signals independently of each other. The anode 191may be electrically connected to the drain electrode 139 of the thinfilm transistor 130 through the contact hole formed in the stepcompensating layer 183 and the interlayer insulating layer 160. Theanode 191 may be a transparent electrode, an opaque electrode, or alaminate structure including both a transparent electrode and an opaqueelectrode. Examples of the material for forming the transparentelectrode may include indium tin oxide (ITO), indium zinc oxide (IZO),zinc oxide, and/or indium oxide, and examples of the material forforming the opaque electrode may include lithium (Li), aluminum (Al),magnesium (Mg), silver (Ag), nickel (Ni), and/or chromium (Cr).

The cathode 193 may be a common electrode which is disposed to overlapthe anode 191 in the third direction Z and the cathode 193 may becontinuously disposed over a plurality of pixels without interruption.For example, the plurality of light-emitting elements 190 disposed indifferent pixels from each other may share the cathode 193 with eachother. Like the anode 191, the cathode 193 may be a transparentelectrode, an opaque electrode, or a laminate structure including both atransparent electrode and an opaque electrode.

The light-emitting layer 195 may be interposed between the anode 191 andthe cathode 193. Within the light-emitting layer 195, holes andelectrons transferred from the anode 191 and the cathode 193,respectively, may recombine to generate light. For example, the holesand electrons are recombined in the light-emitting layer 195 to generateexcitons, and the excitons emit light as they relax from the excitedstate to the ground state. The light-emitting layer 195 may include amaterial that phosphoresces or fluoresces only blue light, a materialthat phosphoresces or fluoresces only green light, and/or a materialthat phosphoresces or fluoresces only red light.

A hole control auxiliary layer such as a hole injection layer, a holetransport layer, or a hole blocking layer; an electron control auxiliarylayer such as an electron injection layer, an electron transport layer,or an electron blocking layer; and/or a charge generating auxiliarylayer may be further interposed between the light-emitting layer 195 andthe anode 191 and/or between the light-emitting layer 195 and thecathode 193, so that the light-emitting efficiency of the light-emittingelement 190 can be increased.

In some exemplary embodiments of the present invention, a pixel definingfilm 185 may be further disposed on the anode 191. The aforementionedlight emitting layer 195 and the cathode 193 may be disposed on thepixel defining film 185. In a plan view, the pixel defining film 185 mayhave an opening partially exposing the anode 191. The pixel definingfilm 185 may isolate the anode 191 and the cathode 193 from each other,and may partition a plurality of pixels. The pixel defining film 185 mayinclude an organic material such as an acrylic resin, an epoxy resin, animide resin, and/or an ester resin.

Next, the counter substrate 201 will be described. The counter substrate201 (for example, a second substrate) may face the light-emittingsubstrate 101. For example, the counter substrate 201 may be anencapsulating substrate that is disposed over the light-emittingsubstrate 101 and encapsulates the light-emitting element 190 togetherwith a sealing member 301 to be described later. The counter substrate201 may include a second base substrate 211, and may further include atouch element layer 231.

The second base substrate 211 is configured to encapsulate thelight-emitting element 190 to prevent the light emitting element 190from being damaged by air, moisture, or the like. The second basesubstrate 211 may be a transparent plate or a transparent film. Forexample, the second base substrate 211 may include a glass material, aquartz material, or the like. In some exemplary embodiments of thepresent invention, the second base substrate 211 and the light-emittingelement 190 may be spaced apart from each other, and an inert gas suchas nitrogen gas may be disposed therebetween. However, the presentinvention is not limited thereto, and the space between the second basesubstrate 211 and the light-emitting element 190 may be filled with afiller or the like.

In an exemplary embodiment of the present invention, in a plan view, thesecond base substrate 211 may include a main portion 211 a having afourth maximum width W_(211a) in the first direction X, a firstprotruding portion 211 b protruding from the main portion 211 a in thesecond direction Y, and a second protruding portion 211 c protrudingfrom the main portion 211 a in the second direction Y and spaced apartfrom the first protruding portion 211 b in the first direction X. Thefirst protruding portion 211 b of the second base substrate 211 may havea fifth maximum width W_(211b) in the first direction X, and the secondprotruding portion 211 c thereof may have a sixth maximum width W_(211b)in the first direction X. Each of the fifth maximum width W_(210b) andthe sixth maximum width W_(211c) may be smaller than the fourth maximumwidth W_(211a). For example, the sum of the fifth maximum width W_(211b)and the sixth maximum width W_(211c) may be smaller than the fourthmaximum width W_(211a). The fifth maximum width W_(211b) and the sixthmaximum width W_(211c) of the second base substrate 211 may be the sameas or different from each other. In addition, the second base substrate211 may have a shape in which the maximum length thereof in the seconddirection Y is longer than the length thereof in the first direction X,for example, the fourth maximum width W_(211a).

The planar area of the second base substrate 211 may be smaller than theplanar area of the first base substrate 111.

For example, the main portion 111 a of the first base substrate 111 andthe main portion 211 a of the second base substrate 211 may overlap eachother in the third direction Z. Further, the main portion 111 a of thefirst base substrate 111 has substantially the same shape as the mainportion 211 a of the second base substrate 211, and may havesubstantially the same area as the main portion 211 a of the second basesubstrate 211. For example, the maximum width W_(111a) of the mainportion 111 a of the first base substrate 111 in the first direction Xmay be substantially the same as the maximum width W_(211a) of the mainportion 211 a of the second base substrate 211 in the first direction X,and the length of the main portion 111 a of the first base substrate 111in the second direction Y may be substantially the same as the length ofthe main portion 211 a of the second base substrate 211 in the seconddirection Y.

The first protruding portion 111 b of the first base substrate 111 andthe first protruding portion 211 b of the second base substrate 211 mayoverlap the second protruding portion 111 c of the first base substrate111 and the second protruding portion 211 c of the second base substrate211 in the third direction Z, respectively. The first protruding portion111 b of the first base substrate 111 may have a larger planar area thanthe first protruding portion 211 b of the second base substrate 211, andthe second protruding portion 111 c of the first base substrate 111 mayhave a larger planar area than the second protruding portion 211 c ofthe second base substrate 211.

In an exemplary embodiment of the present invention, the second maximumwidth W_(111b) of the first protruding portion 111 b of the first basesubstrate 111 in the first direction X may be substantially the same asthe fifth maximum width W_(211b) of the first protruding portion 211 bof the second base substrate 211 in the first direction X, and thelength L_(111b) of the first protruding portion 111 b of the first basesubstrate 111 in the second direction Y may be greater than the lengthL_(211b) of the first protruding portion 211 b of the second basesubstrate 211 in the second direction Y.

Similarly, the third maximum width W_(111c) of the second protrudingportion 111 c of the first base substrate 111 in the first direction Xmay be substantially the same as the sixth maximum width W_(211c) of thesecond protruding portion 211 c of the second base substrate 211 in thefirst direction X, and the length L_(111c) of the second protrudingportion 111 c of the first base substrate 111 in the second direction Ymay be greater than the length L_(211c) of the second protruding portion211 c of the second base substrate 211 in the second direction Y.

The first protruding portion 111 b and the second protruding portion 111c of the first base substrate 111, which are not covered by the firstprotruding portion 211 b and the second protruding portion 211 c of thesecond base substrate 211, may be provided with the light-emittingsubstrate pad unit 170.

At least a part of the display area DA of the display device 1 mayoverlap the first protruding portion 211 b and second protruding portion211 c of the second base substrate 211. For example, pixels are definedin the first protruding portion 211 b and second protruding portion 211c of the second base substrate 211 as well as in the main portion 211 aof the second base substrate 211, and the pixels may contribute to imagedisplay and color expression. Except for an area where a module member601, to be described later, is disposed, the display area DA is formedaround three sides of the module member 601 (two sides in the firstdirection X, and 1 side in the second direction Y) thereby minimizingthe planar area of the non-display area NA and increasing the planararea of the display area DA.

One side edge (for example, a lower edge in FIG. 5 ) of the second basesubstrate 211 in the second direction Y may have an atypical shape suchas a bay, a notch, or a trench, in a plan view. For example, one sideedge 221 of the second base substrate 211 may be partially indented. Forexample, one side edge 221 of the second base substrate 211 may includea fourth edge 221 b, a fifth edge 221 a indented from the fourth edge221 b, and a sixth edge 221 c protruding from the fifth edge 221 a.

The fourth edge 221 b refers to one side edge of the first protrudingportion 211 b of the second base substrate 211 in the second directionY, the fifth edge 221 a refers to one side edge of the main portion 211a of the second base substrate 211 in the second direction Y, and thesixth edge 221 c refers to one side edge of the second protrudingportion 211 b of the second base substrate 211 in the second directionY. The first protruding portion 211 b, second protrusion portion 211 cand fifth edge 221 a of the second base substrate 211 may together forma bay.

In an exemplary embodiment of the present invention, the shortestdistance D₄ from the fourth edge 221 b to the display area DA in thesecond direction Y may be larger than the shortest distance D₅ from thefifth edge 221 a to the display area DA in the second direction Y.Further, the shortest distance from the sixth edge 221 c to the displayarea DA in the second direction Y may be larger than the shortestdistance D₅ from the fifth edge 221 a to the display area DA in thesecond direction Y. In some exemplary embodiments of the presentinvention, the shortest distance D₁ from the first edge 121 b to thedisplay area DA may be larger than the shortest distance D₄ from thefourth edge 221 b to the display area DA, and the shortest distance D₂from the second edge 121 a to the display area DA may be substantiallyequal to the shortest distance D₅ from the fifth edge 221 a to thedisplay area DA.

As will be described later, the shortest distance D₄ from the fourthedge 221 b to the display area DA is larger than the shortest distanceD₅ from the fifth edge 221 a to the display area DA, therebysufficiently securing the width of a portion extending in the firstdirection X (for example, a first linear portion 311 to be describedlater) of the sealing member 301 disposed on the first protrudingportion 211 b.

In addition, the first edge 121 b of the first base substrate 111protrudes from the fourth edge 221 b of the second base substrate 211 tosupport the light-emitting substrate pad unit 170, and the second edge121 a of the first base substrate 111 is aligned with the fifth edge 221a of the second base substrate 211, thereby minimizing the area occupiedby the light-emitting substrate pad unit 170 and further reducing thearea of the non-display area NA.

Hereinafter, a touch element layer 231, including a touch electrodelayer 240, touch wirings, 251, and a touch pad unit 271, of the displaydevice 1 according to an exemplary embodiment of the present disclosurewill be described in detail with reference to FIGS. 6 to 9 .

FIG. 6 is a plan view illustrating a touch element layer 231 of thecounter substrate 201 of FIG. 1 . FIG. 7 is an enlarged view of the areaA in FIG. 6 . FIG. 8 is an enlarged view illustrating a first touchelectrode 241 and a second touch electrode 242 of FIG. 7 . FIG. 9 is acomparative cross-sectional view illustrating a cross-sectional takenalong the line IXa-Ixa′ of FIG. 8 and a cross-sectional taken along theline IXb-Ixb′ of FIG. 8 .

Referring to FIGS. 6 to 9 , a touch element layer 230 including a touchelectrode layer 240, touch wirings 251, and a touch pad unit 271 may bedisposed on the upper surface of the second base substrate 211.

The touch electrode layer 240 may include a first touch electrode 241extending in the first direction X and a second touch electrode 242extending in the second direction Y. The first touch electrode 241 andthe second touch electrode 242 may cross each other. A fourth insulatinglayer 280 may be interposed between the first touch electrode 241 andthe second touch electrode 242 to insulate them from each other. Thefourth insulating layer 280 may include an inorganic insulatingmaterial. Examples of the inorganic insulating material include siliconnitride, silicon oxide, silicon oxynitride, and silicon oxynitride.

The plurality of first touch electrodes 241 may extend in the firstdirection X, and may be spaced apart from each other in the seconddirection Y. The first touch electrode 241 may be a transparentelectrode. The first touch electrode 241 may include a plurality offirst extension portions 241 a having a substantially rhombic shape in aplan view and a first connection portion 241 b connecting the adjacentfirst extension portions 241 a. The first touch electrode 241 may be asensing electrode configured to carry a sensing signal.

The plurality of second touch electrodes 242 may extend in the seconddirection Y, and may be spaced apart from each other in the firstdirection X. The second touch electrode 242 may be a transparentelectrode. The second touch electrode 242 may include a plurality ofsecond extension portions 242 a having a substantially rhombic shape ina plan view and a second connection portion 242 b connecting theadjacent second extension portions 242 a. The second touch electrode 242may be a driving electrode configured to carry a driving signal.

In an exemplary embodiment of the present invention in which each of thefirst extension portions 241 a and the second extension portion 242 ahas a rhombic shape, the first extending portion 241 a and the secondextending portion 242 a may be spaced apart from each other in adirection facing each other (for example, a diagonal directionintersecting the first direction X and the second direction Y in theplane). The first connection portion 241 b and the second connectionportion 242 b may intersect each other so as to be insulated from eachother. For example, the second connection portion 242 b extending in thesecond direction Y may be disposed on the first connection portion 241 bextending in the first direction X, and the fourth insulating layer 280may be interposed between the first connection portion 241 b and thesecond connection portion 242 b.

A mutual capacitance may be formed between the first touch electrode 241extending in the first direction X and the second touch electrode 242extending in the second direction Y. When the capacitance between thefirst touch electrode 241 and the second touch electrode 242 is changedby a user's touch operation, the display device 1 can acquire coordinateinformation about the user's touch operation based on the changedcapacitance. For example, the touch element layer 231 of the countersubstrate 201 can acquire the coordinate information about the user'stouch operation.

The touch wirings 251 may extend from the non-display area NA, forexample, the inner non-display area INA, and may transmit a signalprovided from an external driving element to the touch electrode layer240. For example, the touch wirings 251 may be electrically connected tothe touch pad unit 271 to transmit a signal provided from the secondflexible circuit film 501 to the touch electrode layer 240. The touchwirings 251 may include a first touch wiring 251 a connected with thefirst touch electrode 241 and a second touch wiring 251 b connected withthe second touch electrode 242.

The first touch wiring 251 a may include first portions 251 a 1extending in the first direction X and second portions 251 a 2 extendingin the second direction Y. The second touch wiring 251 b may includefirst portions 251 b 1 extending in the first direction X and secondportions 251 b 2 extending in the second direction Y. In an exemplaryembodiment of the present invention, each of the first touch wiring 251a and the second touch wiring 251 b may be located at least partially inthe non-display area NA. For example, in a plan view, the first portion251 b 1 of the second touch wiring 251 b may be located entirely withinthe sealing member 301.

The touch pad unit 271 (for example, the second pad unit) may be locatedin the non-display area NA. For example, the touch pad unit 271 may belocated at least partially in the outer non-display area ONA. Forexample, the touch pad unit 271 may at least partially overlap the outernon-display area ONA without being located in the inner non-displayarea, and may at least partially overlap the sealing area SA. In thiscase, the touch wirings 251 may at least partially cross the sealingarea SA. The planar area occupied by the inner non-display area INA canbe minimized by disposing the touch pad unit 271 so as not to be locatedin the inner non-display area INA.

The touch pad unit 271 may include first pad electrodes 271 a connectedto the first touch wiring 251 a and second pad electrodes 271 bconnected to the second touch wiring 251 b. However, the presentinvention is not limited thereto, and in an exemplary embodiment of thepresent invention, the ends of the first touch wiring 251 a and thesecond touch wiring 251 b may extend to form the touch pad unit 271 forelectrical connection.

The present invention is not limited thereto. For example, when thelight-emitting substrate 101 including the light-emitting element 190and the counter substrate 201 including the touch element layer 231 arerespectively manufactured, and then coupled with each other using thesealing member 301, the touch wiring portions 251 a 1 and 251 b 1extending in the first direction X adjacent to the sealing member 301extending in the first direction X and the touch wiring portions 251 a 2and 251 b 2 extending in the second direction Y adjacent to the sealingmember 301 extending in the second direction Y were disposed inward fromthe sealing member 301, so as to secure the transmittance of a lasertraveling from the counter substrate 201 to the sealing member 301 andto cure the sealing member with the laser.

The touch pad unit 271 may be disposed adjacent to one side edge of thesecond base substrate 211 in the second direction Y. In an exemplaryembodiment of the present invention, the touch pad unit 271 includingthe first pad electrode 271 a and the second pad electrode 271 b isdisposed adjacent to the fourth edge 221 b of the second base substrate211, but might not be disposed adjacent to the fifth edge 221 a and thesixth edge 221 c. The touch pad unit 271 including the first padelectrode 271 a and the second pad electrode 271 b is disposed on thefirst protruding portion 211 b of the second base substrate 211, butmight not be disposed on the main portion 211 a and the secondprotruding portion 211 c, thereby simplifying the connection structureof the second flexible circuit film 501 and minimizing the area of thenon-display area NA. In addition, there is an effect of securing a spacefor disposing a module member 601 to be described later.

Hereinafter, the sealing member 301 of the display device 1 according toexemplary embodiments of the present invention will be described indetail with reference to FIG. 10 .

FIG. 10 is a layout view illustrating the light-emitting substrate 101,the counter substrate 201, and the sealing member 301 of FIG. 1 .

Referring to FIG. 10 , the sealing member 301 may be disposed betweenthe light-emitting substrate 101 and the counter substrate 201 to couplethem with each other. For example, the sealing member 301 may be broughtinto contact with the interlayer insulating layer 160 of thelight-emitting substrate 101 and the back surface of the second basesubstrate 211 of the counter substrate 201. The sealing member 301 maybe a cured frit. As used herein, the term “frit” refers to a structurehaving glass properties formed by melt-curing a powdered glassoptionally containing an additive.

In a plan view, the sealing member 301 may form a closed curve and maysurround the light-emitting element 190 of the light-emitting substrate101. For example, the sealing member 301 is configured to seal the lightemitting element 190, and thus can prevent the light emitting element190 from being damaged by air, moisture, or the like. The sealing member301 may be disposed in the non-display area NA to define the sealingarea SA. The planar shape of the sealing member 301 may have a shapesubstantially corresponding to the planar shape of the first basesubstrate 111 or the planar shape of the second base substrate 211.

In an exemplary embodiment of the present invention, the sealing member301 may include a first linear portion 311 extending in the firstdirection X and a second linear portion 321 extending in the seconddirection Y.

The first linear portion 311 may have a substantially linear shape. Forexample, each of the outer edge and the inner edge of the first linearportion 311 of the sealing member 301 may have a substantially linearshape extending in the first direction X. The first linear portion 311may overlap the first protruding portion 111 b of the first basesubstrate 111 and the first protruding portion 211 b of the second basesubstrate 211. The first linear portion 311 may be a part of the sealingmember 301 closest to the first edge 121 b of the first base substrate111 and the fourth edge 221 b of the second base substrate 211.

The second linear portion 321 may have a substantially linear shape. Forexample, each of the outer edge and the inner edge of the second linearportion 321 of the sealing member 301 may have a substantially linearshape extending in the second direction Y. The second linear portion 321may overlap the main portion 111 a of the first base substrate 111 andthe main portion 211 a of the second base substrate 211. Further, thesecond linear portion 321 may at least partially overlap the firstprotruding portion 111 b of the first base substrate 111 and the firstprotruding portion 211 b of the second base substrate 211.

The maximum width W₃₁₁ of the first linear portion 311 may be differentfrom the maximum width W₃₂₁ of the second linear portion 321. In anexemplary embodiment of the present invention, the maximum width W₃₁₁ ofthe first linear portion 311 may be greater than the maximum width W₃₂₁of the second linear portion 321. For example, the maximum width W₃₁₁ ofa portion of the sealing member 301 overlapping the first protrudingportion 111 b of the first base substrate 111 and the first protrudingportion 211 b of the second base substrate 211 (for example, the firstlinear portion 311) may be greater than the maximum width W₃₂₁ of aportion of the sealing member 301 overlapping the main portion 111 a ofthe first base substrate 111 and the main portion 211 a of the secondbase substrate 211 (for example, the second linear portion 321).

The difference between the maximum width W₃₁₁ of the first linearportion 311 and the maximum width W₃₂₁ of the second linear portion 321may be about 10% or more of the maximum width W₃₂₁ of the second linearportion 321. For example, the maximum width W₃₂₁ of the second linearportion 321 may be within a range of about 400 μm to about 450 μm, andthe maximum width W₃₁₁ of the first linear portion 311 may be within arange of about 450 μm to about 550 μm. As used herein, unless otherwisedefined, the term “width” refers to a width in a direction perpendicularto an extension direction or a protruding direction. Therefore, widthmay be thought of here as the line thickness of the first linear portion311, the second linear portion 321, and the third linear portion 331, asshown in FIG. 10 .

The first linear portion 311 may be located adjacent to thelight-emitting substrate pad unit 170 and the touch pad unit 271. In aplan view, the first linear portion 311 may be located between thelight-emitting substrate pad unit 170 and the touch pad unit 271. Thepresent invention is not limited thereto, but, for example, when thelight-emitting substrate pad unit 170 and the first flexible circuitfilm 401 are connected through a pressing process and/or the touch padunit 271 and the second flexible circuit film 501 are connected througha pressing process, stress caused by the pressing process may be focusedon the first protruding portion 111 b of the first base substrate 111,the first protruding portion 211 b of the second base substrate 211 andthe first linear portion 311 of the sealing member 301. In addition, thelight-emitting substrate pad unit 170 is not formed on the main portion111 a of the first base substrate 111, so that the pressure per unitarea applied to the first protruding portion 111 b of the first basesubstrate 111 in the pressing process may increase. In the displaydevice 1, according to exemplary embodiments of the present invention,the maximum width W₃₁₁ of the first linear portion 311, which isrelatively vulnerable to stress, is sufficiently wide, so that thedurability of the display device 1 can be increased. The touch pad unit271 and the touch wirings 251 of the aforementioned touch element layer231 may at least partially overlap the first linear portion 311.

In some exemplary embodiments of the present invention, the sealingmember 301 may further include a first curved portion 361 extending fromthe first linear portion 311 and partially curved, and a third linearportion 331 extending from the first curved portion 361 and extending inthe first direction X.

In a plan view, the first curved portion 361 may include one or morecurved portions. The first curved portion 361 may have a partiallycurved shape including at least one curved line having a predeterminedcurvature radius R₆. For example, the first curved portion 361 may be anassembly of curves having different curvature radii.

The first curved portion 361 may include a portion concavely curvedtoward the display area DA (for example, a portion directly contactingthe first linear portion 311) and a portion convexly curved toward thedisplay area DA (for example, a portion directly contacting the thirdlinear portion 331). As used herein, the term “curved portion” includesnot only a case where the outer edge and the inner edge of the sealingmember are formed entirely within a curved line but also a case wherethe outer edge and the inner edge of the sealing member has a partiallylinear section together with a curved section. For example, the presentinvention is not limited thereto, but there may be a partially straightportion between the concavely curved portion and the convexly curvedportion of the first curved portion 361.

The first curved portion 361 may overlap the first protruding portion111 b of the first base substrate 111 and the first protruding portion211 b of the second base substrate 211. Further, the first curvedportion 361 may at least partially overlap the main portion 111 a of thefirst base substrate 111 and the main portion 211 a of the second basesubstrate 211.

The third linear portion 331 may have a substantially linear shape. Forexample, each of the outer edge and the inner edge of the third linearportion 331 of the sealing member 301 may have a substantially linearshape extending in the first direction X. The third linear portion 331may overlap the main portion 111 a of the first base substrate 111 andthe main portion 211 a of the second base substrate 211. The thirdlinear portion 331 may be a part of the sealing member 301 closest tothe second edge 121 a of the first base substrate 111 and the fifth edge221 a of the second base substrate 211.

The maximum width W₃₃₁ of the third linear portion 331 may be differentfrom the maximum width W₃₁₁ of the first linear portion 311. In anexemplary embodiment of the present invention, the maximum width W₃₁₁ ofthe first linear portion 311 may be greater than the maximum width W₃₃₁of the third linear portion 331. As described above, the maximum widthW₃₁₁ of the first linear portion 311, which is relatively vulnerable tostress, is formed to be wider than that of other portions, so that thedurability of the display device 1 can be increased, and the shortestdistance D₂ from the second edge 121 a to the display area DA and theshortest distance D₅ from the fifth edge 221 a to the display area DAcan be minimized. The maximum width W₃₃₁ of the third linear portion 331may be the same as or different from the maximum width W₃₂₁ of thesecond linear portion 321.

In an exemplary embodiment of the present invention in which the maximumwidth W₃₃₁ of the third linear portion 331 is smaller than the maximumwidth W₃₁₁ of the first linear portion 311, the width of the firstcurved portion 361 may decrease from the first linear portion 311 towardthe third linear portion 331. For example, the width of the first curvedportion 361 may gradually decrease.

In some exemplary embodiments of the present invention, the sealingmember 301 may further include a second curved portion 371 extendingfrom the third linear portion 331 and partially curved, and a fourthlinear portion 341 extending from the second curved portion 371 andextending in the first direction X.

For example, the second curved portion 371 may include a portionconcavely curved toward the display area DA (for example, a portioncontacting the fourth linear portion 341) and a portion convexly curvedtoward the display area DA (for example, a portion contacting the thirdlinear portion 331). The second curved portion 371 may overlap thesecond protruding portion 111 c of the first base substrate 111 and thesecond protruding portion 211 c of the second base substrate 211.Further, the second curved portion 371 may at least partially overlapthe main portion 111 a of the first base substrate 111 and the mainportion 211 a of the second base substrate 211.

The fourth linear portion 341 may have a substantially linear shape. Forexample, each of the outer edge and the inner edge of the fourth linearportion 341 of the sealing member 301 may have a substantially linearshape extending in the first direction X. The fourth linear portion 341may overlap the second protruding portion 111 c of the first basesubstrate 111 and the second protruding portion 211 c of the second basesubstrate 211.

The maximum width W₃₄₁ of the fourth linear portion 341 may be differentfrom the maximum width W₃₂₁ of the second linear portion 321. In anexemplary embodiment of the present invention, the maximum width W₃₄₁ ofthe fourth linear portion 341 may be greater than the maximum width W₃₂₁of the second linear portion 321. For example, the maximum width W₃₂₁ ofthe second linear portion 321 may be within a range of about 400 μm toabout 450 μm, and the maximum width W₃₄₁ of the fourth linear portion341 may be within a range of about 450 μm to about 550 μm.

In some exemplary embodiments of the present invention, the sealingmember 301 may further include a third curved portion 381 disposedbetween the first linear portion 311 and the second linear portion 321to connect the first linear portion 311 and the second linear portion321 and partially curved.

In a plan view, the third curved portion 381 may include one or morecurved portions. The third curved portion 381 may have a partiallycurved shape including at least one curved line having a predeterminedcurvature radius R₈. For example, the third curved portion 381 may be anassembly of curves having different curvature radii.

The third curved portion 381 may include a portion curved concavelytoward the display area DA, but might not include a portion convexlycurved toward the display area DA. The third curved portion 381 mayoverlap the first protruding portion 111 b of the first base substrate111 and the first protruding portion 211 b of the second base substrate211.

In a non-limiting example, the maximum radius curvature R₈ formed by thethird curved portion 381 (for example, the curvature radius of a curvehaving the maximum curvature radius when the third curved portion 381 isan assembly of curves having different curvature radii from each other)may be greater than the maximum radius curvature R₆ formed by the firstcurved portion 361 (for example, the curvature radius of a curve havingthe maximum curvature radius when the first curved portion 361 is anassembly of curves having different curvature radii from each other).

As described above, the first curved portion 361 may be located at thebay formed by the edges 121 and 221 of the first base substrate 111 andthe second base substrate 211 in the second direction Y, and the thirdcurved portion 381 may be located at the edge of the first basesubstrate 111 and the second base substrate 211 in the first directionX. The present invention is not limited thereto, but when one side edge121 of the first base substrate 111 in the second direction Y ispartially indented and one side edge 221 of the second base substrate211 in the second direction Y is partially indented, the external impactapplied to the display device 1 may be concentrated/focused in thevicinity of the indented portion. For example, the external impactapplied to the display device 1 may be concentrated/focused in thevicinity of the first curved portion 361 as compared with the vicinityof the third curved portion 381. In the display device 1, according toexemplary embodiments of the present invention, the maximum curvatureradius R₆ of the first curved portion 361, which is relativelyvulnerable to stress, is smaller than the maximum curvature radius R₈ ofthe third curved portion 381, so that the durability of the displaydevice 1 can be increased.
